Overview

The Avid by Merits Vector HD P323 is the super heavy duty member of the Avid Rehab lineup. It is a complex rehab mid wheel drive power base engineered for riders up to 450 lb who need real positioning hardware rather than a basic captain seat chair. The powerbase carries HCPCS codes K0850 K0858 and K0862 and pairs dual in line 4 pole motors with full front and rear coil suspension so heavier riders keep traction and comfort over thresholds ramps and rough sidewalks.

Six wheels stay on the ground at all times. The 14 x 3 inch foam filled drive wheels sit directly under the rider with widened 8 x 3 inch casters front and rear for stability at capacity. Because the drive wheels are centered the Vector HD spins within a 27 inch turning radius which is remarkable agility for a 450 lb rated base and makes tight hallways bathrooms and elevators workable.

Seating is where the Vector HD separates itself from consumer heavy duty chairs. The rehab seat frame adjusts from 20 to 24 inches wide and 16 to 22 inches deep and it accepts power tilt up to 50 degrees power recline from 90 to 150 degrees a 12 inch power seat elevator and power elevating legrests. Pressure management options such as Deep contour cushions and Gel Ovations components can be specified when the chair is built.

Two 22NF MK batteries deliver up to 12.5 miles of range per charge and buyers choose between the simple PG VR2 controller or the expandable R-NET system for multi actuator control. Every Vector HD is configured to order so contact us for a quote built around your seating and funding requirements.

How much weight can the Avid Vector HD carry?

The Vector HD P323 is rated for riders up to 450 lb. Widened 8 x 3 in casters front and rear and 14 x 3 in drive wheels keep it stable at full capacity, and all six wheels stay on the ground at all times. Full front and rear coil suspension keeps traction over thresholds and ramps.

What seat sizes are available on the Vector HD?

The rehab seat frame adjusts from 20 to 24 in wide and 16 to 22 in deep, with backrest heights from 18 to 28 in, so your provider can set the fit. Seat to floor height is 18.5 to 19.5 in. Cushion options such as Deep contour and Gel Ovations components can be specified when the chair is built.

Does the Vector HD come with power tilt and recline?

They are available as configured options. Power tilt goes up to 50 degrees, and power recline runs from 90 to 150 degrees on recline configurations. A 12 in power seat elevator and power elevating legrests can also be added. Each chair is configured to order, so a seating assessment helps decide which functions you need.

What is the difference between the VR2 and R-NET controllers on the Vector HD?

The PG VR2 is a simple, dependable joystick system suited to driving plus basic seat functions. R-NET is an expandable system that manages multiple power seat actuators, alternative drive controls and future upgrades. Riders with several power seating functions usually choose R-NET.

Will the Vector HD fit in tight spaces at home?

The mid wheel drive base spins within a 27 in turning radius, which makes tight hallways, bathrooms and elevators workable. It is 25 in wide and 47 in long. Many home doors are 28 to 30 in, so measure the clear opening with the door fully open.

How far does the Vector HD go on a charge?

Two 22NF MK batteries, 55Ah AGM or 51Ah gel, deliver up to 12.5 miles per charge. Real range varies with rider weight, terrain, temperature and how often the power seat functions are used. Top speed is 5 mph.

Can I transport the Vector HD in a car?

No. Configured weight runs 315 to 416 lb and the chair does not fold. Plan on a wheelchair accessible vehicle, a platform lift or medical transport.

Will Medicare or insurance pay for the Vector HD?

The Vector HD carries HCPCS codes K0850, K0858 and K0862, complex rehab power wheelchair categories. Insurance funding needs a clinical evaluation, a written order and an enrolled supplier. Heavy Duty Mobility does not hold a Medicare supplier number or bill insurance, so a purchase here is a self pay build.
